-043 BLACK FKM 90D O-RING

Ordered as V90043, this is an AS568-043 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 3.489 in (88.62 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.629 in (92.18 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists engine and transmission fluids, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present.

Common environments for this compound include semiconductor equipment, chemical processing, and oil and gas.

Reference part number V90043 when ordering; the item is sold individually. Unit weight is approximately 1.3069 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
